It makes a HUGE difference. My friend owns a dyno, i will try to jump on one afternoon to get some numbers. it does not seem to me to have the issues the stage 1 has with the surges and power drop off described here as being normal with the stage 1: https://www.chevyhhr.net/forums/2-0l-performance-tech-46/boost-level-stage-kit-automatic-24417/ I am not experiencing any of those problems.
also, it increases the speed and the firmness of the shifts, increases the redline and that makes almost as much of a difference in performance as the power increase does. that was another big + that swayed me in the direction of the cortex tuner. it also comes with a 2 year powertrain warranty as well. You would not believe how nice the transmission shifts now, it is like a different transmission. it is really fast and smooth.
you also get the advanced tune ( where you can adjust things how you like) and an economy tune for max mpg.
it has some really cool features on the tuner that datalogs performance data as well.

How true it is, I'm waiting on Vince to dail in his tune
The only problem I see, which I have now is keeping the frt wheels from spining but the hp is great on the open road.
Viva more hp

But none of these options, canned tunes, will top a custom tune. Still, it's great to have the options.

I think any tune would work with the updated MAP sensors but my guess would be not with the program. It may be the same parameters changed as well or may cause a conflict. I bet HPTuner would work with it if they can put HPT on top of the Stage kit.
